MILKING-MACI-IINE.

To all whom it may concern:

Be it known that we, FRANS Josnr Jonanssov and Earns ALBERT OLsoNGo'rI-IE, subjects of the King of Sweden, residing at Stockholm, in theKingdom of Sweden, have invented new and useful Improvements inMilking-Machines, of which the follow ing is a specification,-referencebeing had to the drawing accompanying and forming a part hereof.

This invention relates to improvements in milking machines andparticularly tothe teat supporting members sometimes used in suchmachines, said members bearing, during the milking operation, on theudder so to hold the teat in a desired adjustable position in the teatcup.

The object of the invention is to provide a device of the said kindwhich is simple, durable and easily adjustable both in vertical andlateral direction and which is particularly adapted to be employed inteat cups consisting of a sleeve and a teat operating memberreciprocating therein.

The invention consists, chiefly, in the teat supporting member beingplaced at one end of a rod or the like the other end of which ispivotally and springily attached to the teat cup, or some part connectedthereto, said rod being combined with suitable adjusting means, such asa set screw inserted through a threaded hole in the rod and bearing onthe teat cup or some part connected thereto. This arrangement enablesthe teat supporting member to be adjusted vertically by turning the setscrew. If the teat supporting member is not to be used, it may be swunglaterally into inoperative po sition.

The invention further comprises the con-- struction and combination ofparts hereinafter set forth.

In the drawing, we have shown by way of example, a suitable embodimentof the invention.

Figure 1 is a side view of a part of a milking machine having teatsupporting members according to this invention. Fig. 2 is a plan view ofthe right hand part of Fig. 1.

Referring to the drawing, a is a sleeve inclosing a reciprocatingcompressing member Z) operated from without by a driving device 0. Thesleeve a is supported by a rod d. A pivot pin, screw bolt or the like fextends upward from the said arm 0? Specification of Letters Patent.

through a wide opening in one end of the teat supporting arm or rod 6.Placed between the said rod 6 and a head on the bolt f is a spring 9 thetension of which may be adjusted by turning the said screw. Screwedthrough a threaded hole in the rod 6, at a suitable distance from thebolt f, is a set screw it bearing on the sleeve a. outer end of the rod6 carries a ring i having a size enabling it to be placed about thethickest teats and located just above that part of the sleeve a whichreceives the teat.

By turning the screw it the rod 6 is caused to swing upward or downwardat the bolt f by which the ring 7 is adjusted relatively to the sleevea. If the teat is long, the ring i is moved away from the upper edge ofthe sleeve by which the teat is kept in a raised position relatively tothe sleeve so that the lower part of the teat can be operated by theteat operating member 79. If the teat is short, the ring a is lowered soas to allow the teat to sink deeper into the sleeve. It the teats arevery short, the rod e may be turned around into the position shown bydotted lines by which the teat is allowed to sink into the sleeve 64 asdeep as possible. In the position of the rod 6 shown by dotted linessaid rod may be secured in position by tightening the screw 7 or by therod 6 catching, under the influence of the spring g, into a recess insome part connected to the sleeve, such as the rod (13.

We claim:

1. In a milking machine, the combination with a teat cup, of ayieldingly supportedrod adapted to be swung laterally, a teat supportingmember situated at the free end of the said rod, above the part of theteat cup receiving the teat, and a member adjustably supporting the saidrod.

2. In a milking machine, the combination with a teat cup, of ayieldingly supported rod adapted to be swung laterally, a teatsupporting member situated at the free end of the said rod, above thepart of the teat cup receiving the teat, and a member ad justablysupporting the said rod at a point between the fulcrum of the same andthe teat supporting member.

8. In a milking machine, the combination with a teat cup, of a rodyieldingly sup ported at one end so as to be adjustable in a verticalplane, and adapted to be swung laterally, a teat supporting member situated at the free end of the said rod, above The the part of the teat cupreceiving the teat, and a screw inserted through a threaded hole in thesaid rod and bearing on a fixed part of the milking machine.

4:. In a milking machine, the combination with a teat cup, of a rodhaving a hole at one end, a screw engaging the said hole, a springplaced between the head of the screw and the said rod and tending topress the latter downward, a teat supporting n1em- Copies of this patentmay be obtained for five cents each, by addressing the Commissioner ofPatents ber situated at the free end of the said rod, above the part ofthe teat cup receiving the teat, and a screw inserted through a threadedhole in the said rod and bearing on a fixed part of the milking machine.
